To me it would be well worth machining the bed, may not even need to if you used RM1204 ball-nuts as they're significantly smaller than RM1605. Since you wouldn't have to machine the ballscrews the overall man-hours is probably quite similar.
What machine is this for?
1205 is too small, its for an existing metal working machine not a DIY one, and as such was designed with a 1605 so i would assume thats what it would require, and to be fair i would pay double that if i could get it tuesday, sometimes its about speed and quality not money, it has to be done correctly so, the existing nut is square so i just swap it out, i dont have the time to machine an 800x20x6mm slot in a cast bed, it just dosnt make chronological sence for me, but it may suit others, i know which machine i would rather buy though....
